hey everyone,i am working on a project and i really need some help with interfacing the emotiv epoc with arduino,i was told that it could be connected to arduino for arduino understand it but i dont know how to do it. if someone can please help me then that'll be great!it is for a project and its very important,my email is:http://espare00@yahoo.com

Well i want to connect the Arduino Mini to my PC with the Serial to USB adapter without buying a FDTI Friend (https://www.sparkfun.com/products/9717). This is a LaserTag Project Which is low Budget. Buying a Serial to USB is cheaper than the FDTI. If you still need to know more ask away.

You'll need a USB host shield (https://www.sparkfun.com/products/9947), to plug the dongle into. Then you'll need to know exactly how the dongle presents itself to a USB host (does it pretend to be a keyboard, or mouse, or joystick, or something else entirely?), and write an appropriate USB driver sketch to run on the Arduino.

I was just outlining the likely steps required. There was no intention to imply a level of difficulty. If the dongle presents itself as one of the standard HID devices, it might not take too long to get something useful out of it. As they claim that the dongle "requires no custom drivers", that would suggest it is a standard class compliant device. Downloading the SDK might well reveal some useful information. There is a free 'lite' version, but it requires registration.
